Paper Title:
The Process to Recover Soda Ash from Mining Solution in a Pilot Plant
  Abstract

The process to recover soda ash from mining solution is combined CO2 stripping with falling film evaporation, and the stripping operation is the key step in the process, the processing installations include a CO2 stripping tower, falling film evaporators and other accessories. The stripping and combined operation(linking CO2 stripping with falling film evaporation) are implemented to examine tower operational conditions and ascertain how to efficiently concentrate mining solution, respectively. As a result, after the better design scheme(17-meter height packing) is evidently proposed and the process design is also favorably optimized, such as diminishing equipment sizes in a following industrial scale. Besides, the work also analyzes the solubility of Na2CO3 and NaHCO3 in H2O and discusses its probable equilibrium in the operation.
